[orca-list] Aria-hidden: confirmation in newer Orcas?

[Mallory van Achterberg <stommepoes stommepoes nl>]

Hey guys,

The mighty Steve Faulkner has put up a sort of status-update
on aria-hidden HTML properties for us web devs, to show
that browser and AT support is slowly getting better. What he
did not have was Orca or Window-Eyes results.

I'm still running Precise, I still have Orca 3.4.2 and since this
is my work computer where compiz and everything else seems
slightly unstable, I don't dare upgrade Gnome or anything. In 
fact, launching Orca always gets me compiz crash alerts.

Anyway I want to ask if someone running a newer Orca, like 3.8.x
could go through Steve's test page and see if you get the same
results as me: aria-hidden doesn't seem to mean anything in Orca
in Firefox 24 (Steve said it was fine that I couldn't test FF 25).

Here's his post: http://blog.paciellogroup.com/2013/11/html5-accessibility-chops-hidden-aria-hidden-support/

Here's the test page, it's pretty easy to go through it:
http://www.html5accessibility.com/tests/hidden2013.html

First is a list of AT/browsers he did manage to test, and then a
table showing the results. So the second column shows what you
should get if everything passes.

I got
1. Fail (aria-hidden doesn't hide content from Orca)
2. Pass (HTML 'hidden' attribute hides content)
3. Pass (display: none hides content)
4. Pass (off-screen CSS positioning, still hear content though that
should be *negative* 9999px)
5. Fail (aria-hidden set to false doesn't reveal content to Orca)
6. Fail (same as above)
7. Fail (aria-hidden doesn't hide content from Orca)

5 and 6 are failing in two other screen readers in Firefox 25 while 1
passes so these could be Firefox letting other hiding techniques 
override aria-hidden, but if Orca 3.8.x has different results it
could mean something else.

This is just a nice-to-know for developers, otherwise Steve will still
get my results at least and we all know Joanie's doing a big
overhaul of Absolutely Everything so it might also be worthwhile to
worry about testing these a few versions later. But it would be
nice to know where bleeding-edge is right now on this.

Thanks in advance.

cheers,
Mallory
